INVENTOR ICH-LTL E- Euvtn-LEL BY J ATTORNEY 5 Patented Jan. 4, 1944V UNITED STATES PATENT OFFICE csnrnmse om mm c. Gama. springfield, ma. Appiiefion Amst 21, 1941, serai N. 40am z claims. (ci. liz-ss) (omiten under the m of March 3.21883. amended April 80, 1928; 370 0. G. 757) l The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

The subject of this invention is a cartridge clip of the type shown in my U. S. Patent 2,121,792 and intended to hold a double row of cartridges in staggered relation and to be inserted therewith into the receiver of a gun. l

The purpose of this invention is to provide the back plate of the clip with ribs forming rails for the base of the cartridges and to provide the side walls with outwardly directed ribs adjacent the the correerence, the clip consists of a .back plate 5 and spring-pressed side walls 8 6 which converge forwardly and are formed with inwardly curved ends 1 1. Thel side walls adjacent the back plate have outwardly extending ribs 8 8 which serve to guide the clip into the receiver of a gun and hold itin position therein, tting into grooves ln the receiver for such purpose, and also inwardly extending beads or ribs 9 9 which engage in front of the extracting rims A of the cartridges B and retain them in position in the clip.

As shown in the patent the back plate is provided with generally transversely extending arcuate ribs IU which stiffen the plate and are so formed as to resist distortion of the clipdue to the torsional strains set up therein by reason of the staggered or diagonal position of the cartridges loaded ln the clip.

At the forward edge of each side wall 6 an inwardly pressed rib Il is provided to.reduce frietiorial contact of the cartridges with the side wall and thereby relieve the follower of the gun of considerable effort in elevating the cartridges to feeding position.

The elements thus far described are all present in the clip of the patent, By reference to Fig. 3 of this application it will be noted that the guide ribs 8 provide an internal channel or groove I2 whose width is 'substantially twice the thickness of the rim A of the cartridge. The

dimension of the groove is identical with that or the patent and is established in formingv the guide rib without decreasing the bending radius beyond a value which impairs the inherent resiliency of the side walls 8 8. As a consequence of the excessive width of the groove I2, cartridges may be loaded in the clip of the patent with unequal longitudinal positioning and overlapping rims and with improper bearing contact with the side walls. Furthermore some of the cartridges will have their bases riding on the back plate whose surface is roughened by the stiifening ribs l0 and maybe covered with dirt.

In order to eliminate the foregoing objections the back plate is provided with a plurality of inwardly projecting and longitudinally extending preferably parallel rails or ribs 13 13 although it will be understood that the ribs may be arranged in other than parallel relation. While only two ribs are shown and suillce for the purpose it is obvious that additional ribs might be provided. The ribs I3, (which also serve to stiien the back plate) are formed by deforming the metal of the back plate by pressing it inwardly from the outside. As shown in Fig. 1 the ribs i3, laterally define the stiiening ribs I0 and as seen in Fig. 3 they are spaced laterally a slight distance from the ribs 9.

The ribs I0 project inwardly towards the rib 9 an amount which is predetermined to allow Just suillcient space to accommodate the rlrn A o1' the cartridge. By virtue of this arrangement the portion of the cartridge directly in front of the cannelure will have a substantial bearing on the side wall 6. The rims of all of the cartridges in the stack will lie in the same plane and elevation of the stack by the follower of the gun will be facilitated. 'I'he spacing of the bases of the cartridges from the back plate prevents interference with the movement of the stack by dirt or sand which may have accumulated on the back plate and also facilitates removal of the sand from a loaded clip.

In double-row en bloc clips of this type the full stack of cartridges is normally held against removal by the pressure exerted by the side walls. When the clip is in a gun the feeding of the first or uppermost cartridge from the clip to the `gun barrel would resuit in the removal of the pressure of the side walls on the stackexcept for the action of the follower of'the gun which elevates the remainder of .the stack. However when only two cartridges remain in the clip the pressure of the follower may readily cause Jamming or crossing ofl thm two cartridges because the iront portions of the side walls-B-U may spread. A In order to eliminate this 'disadvantage the side walls l-l are provided with an ontwardly directed rib .I4 which is parallel .to and sdioins the-rib u. The ribs u in addition to'serving as stlilenershave' the function of engaging the walls oi the receiver of the asse, 1o?

tridges in staggeredlrelation comprising a back plateand side walls, inwardly and longitudinally gun and prevent spreading oi.' the side walls Q and Jamming of the cart dges.

Because oi' the taper of the cartridgesthe distance between the ribs Ii-Ii of a loaded clip is considerably less than the distance between the guide ribs 8 8, Since the sides of the receiver are parallel the provlsionoi' the ribs I 4 eliminates the loose t of the clip in the receiver and maintains the side walls against spreading beyond their normal cartridge compressing position. The distance between the ribs N-Il is only slightly less than the distance between the guide ribs 8 8.

I claim: l

i. Lelip for holding a double row of carextending ribs in the back plate adjacent the side walls, oppositely' disposed longitudinally and outplate and inwardly and longitudinally extending heads at the juncture o! the guide ribs and side adapted to enter the groove at he cartridges. the said ribs and beads cooperating and acting upon one side of the cartridge base to hold the bases or said cartridges in alignment and support them above the major portion of the interior of the back plate. 2` The cartridge clip as claimed in claim 1 characterized in that the side walls ofthe clip adjacent the front edges thereof are each provided with an outward and horizontally extendlng rib arranged to contact with the sides of the receiver of the gun to prevent the side walls from spreading beyond their normal cartridge compressing position.
